As I understand it, the basic theory is that incoming charged particles provide additional cloud condensation nucleii (like the cloud chambers used as detectors in early subatomic physics), that the
rate of incoming particles is modulated by the
magnetic fields of the sun and earth, and that therefore the amount
of cloud cover varies with the particle flux, which in turn drives climate, so we can stop worrying about CO2.
